Brake ON/OFF Switch

PURPOSE

The Brake On-Off (BOO) switch detects braking action (deceleration). In response to the BOO signal, the Powertrain Control Module (PCM) 
modifies idle speed, air/fuel ratio, torque converter clutch operation on A/T applications, and A/C compressor (if equipped).

OPERATION

Switch contacts are closed when the brakes are APPLIED.
